Here are some shots from the Koni installation. I set them at the mid-point on the rears and 1/4 tighter on the fronts. Driving impressions as follows (I wish I was more articulate, but here goes).
They are markedly better than stock. They are much more firm, turn-in is nice and crisp, steering input is more immediate. At-speed lanes changes are very flat. I have only driven around town and then about 1.25 hours of freeway thus far. Ride is a little more harsh, but not bad.
Overall: I highly recommend the Koni/Swift combination. It makes the Z feel like it should.
As always, Reps welcome and will be returned!!!
